To all whom it may concern:

Be it known that we, CHARLES HENRY KENNY, of the city of VVi-nnipeg, in the Province of Manitoba, Canada, and MAL- COLM'lWCll IILLAN, of the town of Gladstone, in the Province of Manitoba, Canada, have new and useful improve ments in Grain-Car Doors, of which the following is the specification. v

()ur invention relates to grain car doors and the object of the invention is to provide a strong and durable metallic door which can'be quickly released from a car when desired and which can be quickly placed and stored in the open position within the car.

Further objects of our invention will be hereinafter more fully described and particularly pointed out in the claims.

It consists essentially in a door formed from two metallic sections a corrugated lower section and a reinforced upper section, releasable means carried by one of the door posts adapted to engage with the ends of the sections and to be withdrawn within the doorpost, means allowing for the folding of the upper section, and means for raising and automatically locking the lower section in the raised position, the parts being arranged and constructed as hereinafter more particularly described.

Figure l is a front elevation of a car supplied with our door, the door being showirin the closed position. Fig. 2 is an interior view of the car as in Fig. 1. Fig.

3 is a detailed side elevation of-a portion of the lower section of tlie doorshowing the lirtks as they appear when the section is locked with the door raised.

In the drawings like characters of reference indicate corresponding parts in each figure. V

6 is the roof of the car and 7 are the face boards at the side of the door posts.

8 is the inner wall of the car. The grain door is formed with a lower section 9 and an upper section 10, which when in the closed position overlap the one on the other so as to prevent leakage of grain between them. The lower section is formed from corrugated metal with the corrugations running longitudinally of the section and is of Specification of Letters Patent. Application filedAugust 5, 1909.

a height which it is usual to employ with the heavier grams such as wheat.

11 are Z-shaped bars firmly secured to the ends of the lower section by bolts 12. It will of course be understood that the bars will have to be fastened to the section'in such a manner that there will be no possibility of grain escaping at the joint formed between theportions. The Z-bars are employed to give flat'ends to the section. This might be done by rolling the ends of the section after corrugating but we consider such a more expensive manner of constructing the door. p

The door post 2 is provided with an angular vertically extending groove or channel which receives the arm of the Z-bar appearing at the adjoining end of the section 5) when it is in its closed position.

The door post 1 has a verticall) extending angle bar 18 secured to its inner face forming a recess which admits a vertically extendingchannel iron plate 20 slidably between its inner face and the face of the post. The plate is adapted to receive'the extendingarm of the Z-bar at the adjoining end of the lower section and it is secured within the recess by means of straps 2i fastoned at their ends to the plate and looped around bolts 22 passing. from the bar into the post. The straps are curved so as to give a different pitch to the various slots with the'result that the plate 20 is withdrawn within the recess more quickly at the top than at the bottom when raised upwardly, as will shortly be more apparent.

The upper endof the plate is provided with an extending portion 20 which is pivotally secured by a pm 24 to a link 25 pivoted to the post by a pin 26. v a 27 is a .U-shaped rod passing through the cross beam 3 above the upper end of the plate .20, the ends of the rod appearing the one 27. at the interior and the other 27 at the eXterior of the car. The end 27 of the rod isnnited with the pin 24 by means of a link 28 and the. end 27 is connected through a rod 29 with a hand lever 30 fastened to the face boards 7 by means of a bolt 31. T

32 is a track secured to the beam 3 andpassing from the interior of the car ,to the exterior.

33 are opposing bracketsfirmly secured to the lower section of the door and having bars 34 pivotally secured thereto by pins 35.

The bars are secured'through chains 36 with which have the ends adjoining the cross bar bent at 43. The upper section 10 of the door is formed from two portions 10 and 103 secured the one to the other by hinges 44. The section is reinforced by angle irons 45 and the upper portion 10 has its lower edge overlapping the upper edge of the lower portion'at 46 so as to form'a tight joint to prevent the leakage of grain. The ends of the upper section are designed to be received by'the channel in post 2 and the plate 20 in the same manner as are the ends of the lower section. When it is desired to store the upper section of the door the lower portion 10 is folded backwardly on the upper section 10 and is held in this position by a grain.

' pin 47 carried by the upper angle iron of those 45. The in has a lug 47 thereon which prevents it escaping from the angle iron. 7

'48 are chains suspending the upper section from the track.

In order to understand the features of the door we will now describe its operation assuming it closed and the car filled with The, lever 30 is thrown upwardly which movement causes the arms 27 2 and 27 of the rod 27 to pass .upwardly. The arm 27" carries with it the-link 28 which raises the' channel plate 20 the upper end of the plate swinging on the center formed by the pin 26. This causes the channel iron plate to withdraw within the recess and finally disappear so as to free the adjoining edge of the sections. The upper section is freed before the lower section and can be renioved first if desired. As soon as the ends of the sections have been, released they swing out wardly under the pressure of the grain and free it from the car. Before finally cleaning out the grain remaining within the car the upper section is folded as already described and passes to the interior of the car. The

lever 30 is rotated in the direction indicated by the arrow so as. to bring the links 42 to the position shown in Fig. 3 where itwill be seen they lock automatically together. The upper ends ofthe bars 34 swing away from each other and their action-on the chains cause the section to be raisedclear of the floor of the car and remain in the raised position until released by the lever. When this is done the section is also stored within the car against the wall 8.
